SAMUEL THOMPSON, OF MORRIS, ILLINOIS.

DOOR-HANGER.

SPECIFICATION forming part of Letters Patent No. 634,041, dated October 3, 1899.

Application filed May 10, 1899. fierial No. 716,216. (No model.)

To all whom it may concern.-

Be it known that I, SAMUEL THoMPsoma citizen of the United States of America, re

siding at Morris, in the county of Grundy and State of Illinois, have invented certain new and usefulImprovements in Door-Hangers, of which the following is. a specification.

This invention relates to certain improvements in door-hangers of the class wherein ball-bearings are used, which improvements are fully set forth and described in the following specification and claim, reference being had to the accompanying drawings and the letters of reference thereon,forming a part of this specification, in which- Figure 1 is a side elevation of the doorhanger as it would appear resting on a track and having a door attached to the hanger. Fig. 2 is a central verticah section of Fig. 1, looking toward the right of the figure; and Fig. 3 is a perspective view of the detachable block which rests upon the ball bearings, which in turn rest upon a track.

Referring to the drawings, A is a hangeriron formed V shape and having a door F, attached to its two depending arms by means of bolts or screws J. I

B and R are a pair of plates formed so as to have the matching and corresponding semicircular grooves or channels B and B respectively, forming, when secured to the hanger-iron A, a raceway for the balls 0 to travel in around the solid block K, which is secured between said plates B andR and within the raceway formed by the grooves B B as shown particularly in Fig. 2, and held in its proper place by means of the bolts H H. The lower or bottom portion of the plates B and R terminate, respectively, in the downwardly-extending flanges E and S, arranged far enough apart to admit a track T between them, and upon which track the balls 0 travel, the said flanges E and S serving to retain the hanger upon the said track,

The two plates B and R are secured to the hanger A by means of the bolts or screws G,

and they may be made of sheet metal stamped in the form shown for forming the race-channel, or they may be made of cast metal, if desired 3 but preferablytheyshould be stamped be the case where the said'plates rest directly on the balls through the medium of inwardly-projecting flanges struck on said plates or in cases where two blocks are used between said plates and formed so each is provided with half of a groove which rests on the balls, so they are liable to spread the two blocks apart, and thus permit the hanger to drag on the track.

I am aware it is not new to provide a doorhanger with ball-bearings, especially in cases where the balls are so arranged as to be liable to spread the plates of the hangerapart or in cases where the part resting-on the balls consists of a thin horizontally-arranged plate, which is liable to be bent or sprung upward by the weight of the door. My invention therefore consists,essentially, in the use of the two plates B and R, struck up so as to have the channels forming the raceway for the balls and having the integral track-guards E S and the single solid block K made, preferably, of steel, secured between said plates within the race-channel or raceway, around which block the balls travel as the door is moved in either direction, the said block K sustaining the entire weight of the door through the medium of the balls. In operation the door may move in either direction, as it rests on the track, through the medium of the bal1s, which causes the balls to travel around in said raceway in either direction and without danger of spreading or crushing the parts resting on the balls, the whole forming a very cheap and durable hanger for very heavy doors, such as barn-doors.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows, to wit: In a door-hanger the combination with the hanger-iron A, the plates B and R respecor channels B and 13 forming an endless raceway for ball-bearings, and having respec- V tively formed to have the matching grooves tively the integral guide-flanges E and S, the

adapted to rest and travel on said balls subballs 0 arranged in the raceway formed by stantially as and for the purpose set forth. said grooves in such manner as to rest and 1 1 travel on a track located between said guide.- SAMUEL 1 HOMPSON' flanges, and the block K conforming to the form of said raceway and secured to and be- \Vitnesses:
